What kind of temperature is that middle card on the motherboard running at? Seems VERY cramped for a non-ref style card. I shifted cards about a bit. The center card of the MSI RX 470 is about 72. I will post gpuzGPU-z The hottest card is the RX 480 at 76 The card you asked about is 67 all cards on 1 piece of plywood  all temps good 75 or lower  66c  584 watts at the wall  |

$175 USD Programmed and Ran for 24hrs. Hynix memory, strapped 1500. I will sell for BTC. Free Shipping in the USA. No International Shipping I had a 7 gpu system and the customer wanted a 6 gpu system. Please ask questions. I would have to mark it up if I put it on eBay or Amazon. Here are the details on Amazon: http://a.co/bUwfhEz Yeah. I will take it. My zip is 07731. Any play on price? |

Not to argue but here goes.
the 14/16 chip size has issues even with intel.
Basic reason is an electron has a width set by God or the universe or whatever you believe.
Therefore the smaller a chip gets the tighter it is for the electrons to be squeezed into behaving correctly. Ie the etchs in the chip are so freaking small you get crossover or leaking or bleeding of electrons into the wrong spots.
so 14/16 is getting close to the smallest size possible for electrons to fit.
yeah 10 then 7 then done. (we need to be able to go beyond electrons)
So it is not that chips are poorly made it is that it is hard to make chips this small.
That said The shit chip pile may be:
30% fully dead
30% so so
30% good
10% great
this is for 1387 chips
maybe 1385 chips were
10% dead
30% so so
30% good
30% great.
So bitmain is trying to come up with ways to use the 14/16 nm chips
Just wait for 3 years when the 10nm come out they will be worse then these.

With the newest software, based on the code, you should be able to run A4, A6, A721 and A741 with the same raspberry pi.
on the same daisy chain at the same time? pi >>>>>>> 721 >>>>>>>721 >>>>>>> 741 would be nice to see them say this. I would be annoyed further to find I can not do the chain above. Frankly I guess I am just in a crappy mood today so rather then post I will sign off here. |

BTC sent
Thanks I see it.. so sold it is! |

Any idea on whether they'll accept bitcoin for payment? I didn't order the 721's after people were stating that they required bank wire. Just curious if they've resolved this -- cannot find an answer on their website.
They do accept BTC. Yeah and after they charged me they stopped charging 25 use fee for using btc. So they owe me 25 usd in btc . They don't reflect this in my account that they will give be a 25 usd credit since they stopped charging the fee. They also give only 90 day warranty. They also do not say if the 741 will run on the same controller as the 721 To be clear I want to run 2 721s and 1 741 on the same controller. Which I purchased from them along with the two 721s. They also marked the two units I purchased as aluminum and I was charged 80 In taxes by fedex. So frankly I am not pleased with them. |

Most batches have been released for sale at 23:00 Beijing time (GMT +8) and friday has been a quite frequent day.
So, Do you mean It could be in stock today? They may. But you need to check every 1/2 hour for cancelled sales for the next day or two. As this could happen. Most likely you won't see anything and will need to wait until mid February |

The 8x4x4x + gen 2 trick didn't work ..  Did you try ps_jb's suggestion? I tried to add the GPUs one by one after the first 3 GPUs (on 16x slots) , and with those settings : 8x4x4x and Gen1. I managed to get 5 recognised but with lot of battle : many restart, unplug and replug. I don't know why it didn't work straight. I then added the 6th , and I got it recognised but it is stucked with the 43 error code, and the "6xgpu registry hack mod" even in administrator mode doesn't work to get it working. So for now , it's mining with 5 gpus , and I continue searching for ideas about the 6th. Never had this problem before with h81 pro BTC mobos ... (it's my first MSI z97) To Citronick, I understand your advice. But depending on electricity price, customs cost, place available, noise acceptable, electricity available, GPUs costs (sometimes good deals), and abiity to resell gear, everyone will have a different answer to the question .. For me, pandaminer is not good right now. Sure I'm loosing lot of time dealing with problems, and I would like to get rid of it. But in the end, in my particular situation, (different from your particular one), pandaminer could be a loss in the end. point taken - vg54dett. Like what Philip shared, the 4xGPU Biostar Z170 mobo is so far the best format and also cost efficient; good after sales opportunities too. I have 5 x rigs like the Biostar and have chosen that format for all new rigs... until Pandaminer came along. I like the biostar z170. Use a m2 ssd. Use an evga 750 p2 psu or a rosewill quark 850. Small size fast build. As for six card builds such a time waster always an issue or 2 or 3. I have 1 h81 and if you only use 4 cards it works great. So that's what I do with it. And if you don't use a piece of shit celeron or pentium psu . I have a i5 4570s in it it runs really good. |

if you are in the usa I can sell you 1 card and provide software to mine eth and software to mine zec
what is your psu? as gpus pull power.
if you look at my trust rating it is good.

The biostar z170's are reliable no riser issues. and they look good at night with the msi rx 470's here are six 4 card rigs  |

Philip is correct - the CPU fan is on the outtake side (back) not the intake (front) side.
This is logical since pulling air out would give better results to cool down CPU.
No point putting an intake fan for CPU hole - the blank hole/vent is more than sufficient.
the cpu exhaust = 89 f only 1 fan the gpu exhaust = 101 f 2 fans this is with the fans at 9 volts in a 87 f garage |

The 8x4x4x + gen 2 trick didn't work .. Did you try ps_jb's suggestion? not to be a wise-ass here.... but honestly, these nightmares, hours of testing, ancient 6xGPU hacks, registry hacks, messing with risers & BIOS settings, crimson drivers, etc.... all of these downtimes could have been mining time and making good money. After personally building my currently rigs from scratch (all 33 of them)... I appreciate the coming of Pandaminers. Having said that, I now have more time learning software and Linux, and less hardware. Just sharing my 2 cents and I know some hardcore miners may have different views. Nvidia rigs, much easier  (for now at least  ) now on a persnnal POV, i think an AMD rig is really interesting to learn alot of good stuff. But yeah, it seems to be lenghty to get something solid & stable, even with the thousands experience feedback from other peoples. The panda look good, but it's kinda like the ASICS, high price, long ROI, and very low warranty time. Those type of things make me cringe, and i prefer to go GPU mining the normal way because of that. Amd run very good on the biostar z170. |

and losing about 80 to fedex because they wrote aluminum not computer on the invoices. Oddly enough same happened to me with the 1st R4 I got from Bitmain wheny they were briefly only DHL or FedEx: On shipper it lists 'Aluminum' and FedEx dinged me for $35 because of it. My 2nd R4 ordred last week had UPS back as option. Used it, got miner yesterday with no extra charges... Yay FedEx... UPS likes to send random bills for ~$25 a piece weeks later. With Fedex, just call them up and tell them it's a computer and they remove the customs tariff. According to the last Fedex guy I talked to, Bitmain is using a customs code that doesn't match anything in the database. Bitmain has not been an issue. Avalon has been an issue. In any case I will attempt to fix the FedEx issue on my side. If I can fix it Avalon would only owe me 25 usd. Frankly in order for me to buy from them they would need to send me the $25 they me off on the first two 721s. And somewhere someplace let us know can 721s run with 741s on the same chain . Hint to Canaan offer 180 day warranty. Bitmain finally did this it would help,your sales. |

So total turnaround from shipping via USPS from NYC and them sending back* was 2.5 weeks. However, I received a brand new 12/TH S9 to replace my defective 11/TH. Serial numbers, firmware corroborated.
The new 12/TH has been running flawlessly 24/7 for almost 3 weeks.
In retrospect it would have been worth it to pay for repairs at bitmainwarranty.com as the shipping out cost and lost mining time probably was about the same as what they would have charged for an out of warranty repair. But it appears that they replace units too according to other forum threads I've read. Must be Bitmain or have a very close association with them since their help desk software was exactly the same.
Bitmainwarranty is in some kind of business partnership with bitmain . They have two or three locations outside China to do repairs. They are better if you have out of warranty gear and live in the lower forty eight states. |

87$ then?
Friday at 910pm EST it drops to $87. But for you it is $87 right now. AS YOU HAVE BEEN POLITE! Friendly etc. and I will toss in a riser for free. |

Just sharing my 2 cents and I know some hardcore miners may have different views.
citronick I would love to buy 2 of them instead of my two self-made rigs, but I can place them only inside of house. And one is close to living room with TV I believe Philip has experimented all the fan mods successfully, and with Eliovp's custom ROM and Linux efforts; this will result in a nice & power friendly home GPU miner, good enough to be place near the TV. For me I will take the custom ROM and Linux, and would leave all the stock fans intact because the Pandas will be shipped to Labrador mining with shit oem software and a 20 dollar mod fan volts drop to 9 vs 12 fan watts drop from 80 to 40. this is with the gear using 900 watts. I believe watts will drop to 750 with new software which will allow my mod to do 9 volts and 32 watts vs 80. you won't quite be low enough to run a panda next to a tv. but in a room with an open window and a closed door it would be okay. I am waiting for the soft ware from Eliovp for final tests. I sold 11 gpus and some mobos. I have a very nice 2 card case build I have more gpus I have more cpus I have ram. I will be running 27 msi rx 470's 6 biostar riser rigs. z170 with 4 rx 470's each 1 aorus gigabyte z270 with 3 rx 470's here is my review of the new aorus. https://www.newegg.com/Product/Product.aspx?Item=N82E16813128966I have yet to up date it as it runs 4 cards 3 in slots 1 in a riser. the review reflects my 3 msi rx 470's and not the powercolor red devil in a riser added to it. Eventually I may go all pandaminer time will tell. |

Nice to see more numbers,
What is in place of this phantom 9th fan ? a empty hole with no fan, nothing (no hole no fan) ?
To put a outtake fan for CPU would really be overkill, as per Philip's review. The vent/hole for CPU is more than enough since intake fan nicely pushes air out to cool the CPU.
no it will not work.
So the hole is on the side that bring air into the panda, not the side that expel the air outside ? there are 10 holes with 9 fans and 1 empty space the empty hole is on the intake side The two statements in red sound contradictory, so I'm still unclear on the fan configuration. How many fans pull air into the panda, vs how many blow air out? If you have 5 intake fans and 4 exhaust, it's good because you have positive pressure inside the panda, which helps limit how much dust gets in. OTOH, if you have 4 intake fans and 5 exhaust, you have negative pressure, which means the panda will pull in air from the remaining 10th fan hole and possible from other cracks/clearances... my unit has 4 intake and an empty hole. it has 5 exhaust and the cpu uses 15 watts with 1 killer fan and the empty hole 2 gpus use 180- 220 watts with 2 killer fans in push pull setup. there simply is no need to worry about the cpu cooling the stock fan is 2x or 3x what is needed. |
